Abstract

L'invention concerne une installation de pompage (10) qui pompe un fluide, notamment de l'eau et plus particulièrement de l'eau de mer, au moyen de l'action des vagues. L'installation (10) est ancrée (62) dans le fond (60) d'une masse d'eau. Un grand flotteur principal (24) et un petit flotteur secondaire (28) sont respectivement reliés par une longue attache (26) et une attache courte (30) à un levier (16) aux extrémités opposées de son pivot (18). En surmontant la résistance du petit flotteur (28) submergé, une vague soulève le grand flotteur (24), ce qui fait pivoter dans un sens (64) le levier (16) ainsi qu'un arbre associé (18). Lorsque la vague passe et l'attache (26) se détend, le flotteur (28) rappelle le levier (16) et l'arbre(18), ce qui produit un mouvement alternatif servant à entraîner la pompe, telle qu'une pompe péristaltique (14), une pompe à palettes, ou autres.
